Josh Hutcherson has joked that Jennifer Lawrence has become an "Oscar monster" since winning an Academy Award for Silver Linings Playbook.

The Catching Fire star, who appeared with Lawrence in The Hunger Games before her awards success, sat down with Liam Hemsworth to discuss the blockbuster sequel with Digital Spy.

"It's really sad to see her downward decline in personality in general, her awareness of other people's emotions," Hutcherson quipped. "She's become a real Oscar monster!"

Asked if there was any scene that took him by surprise in the finished movie, the actor replied: "The monkey fight scene was cool to see. A lot of elements had to come together and develop in a meaningful way to create that scene."

Hemsworth also spoke about filming Gale's intense torture scene, while Hutcherson revealed which '90s singer-songwriter he become a fanboy of recently.

The Hunger Games: Catching Fire opens in UK cinemas on November 21 and November 22 in the US.
